BEAUMONT — The second of two men who terrorized the Port Arthur community and ultimately killed a young mother has been found guilty for federal violations.

Sabino Orlando Martinez, 35, of Port Arthur, was found guilty by a jury of conspiracy to interfere with interstate commerce by robbery, conspiracy to use and carry firearms during a crime of violence and conspiracy to possess firearms during a drug trafficking crime during a two-day trial before U.S. District Judge Marcia A. Crone on Thursday.

After the opening statement by the prosecutor, the defendant pleaded guilty to conspiracy to possess with intent to distribute cocaine and methamphetamine. The trial proceeded on the remaining three charges of which the jury found him guilty after about one hour.

The federal charges are related to the May 14, 2010 shooting death of Allison Neil Clark on West Port Arthur Road in Port Acres.

Clark’s family was on hand along with law enforcement and federal representatives when the announcement was made outside the U.S Attorney’s Office.

Clark’s mother, Sharon Neil, spoke to media said that Thursday’s guilty verdict brings some closure to the family.

“I never thought I’d see this day in my life,” Neil said. “We’ve very excited. We want to thank the community, the Port Arthur Police Department, the fed’s who worked on this.”

Closure came a few years back, the mother said, after her son-in-law and Clark’s husband, Josh Clark, was cleared as a suspect.

The victim’s aunt, Debi Neil Atkinson, also spoke on the verdict and its meaning.

“We know this is not going to bring her back but now we know what happened,” Atkinson said. “We have justice.”

Family members sat through the recent trial and saw, face to face, the man who pulled the trigger.

After the press conference the widower noted that a piece of jewelry on his tie was actually one of his deceased wife’s earrings. Near him were their two daughters, Cadence and MaKayla.

Clark, 24, and her then 3-year-old daughter were going to Walmart to buy diapers and a gift for a niece when she was shot while driving her Ford Excursion south on West Port Arthur Road on May 14, 2010.

She was able to bring her vehicle to a stop and put her hazard lights on before succumbing to her injuries. She was found by a passing motorist, who was also a neighbor of her parents, according to an archive story.

She had left her 1-year-old daughter at home with her husband, Josh Clark.

Acting U.S. Attorney Brit Featherston called Thursday a great day, as it was the culmination of years of police work.

“The conviction of Sabino Orlando Martinez concludes the prosecution of two very dangerous men, who for more than 10 years terrorized innocent Jefferson County victims by robbing, threatening, exploiting and eventually killing one of their ‘lambs’ they targeted for attack and theft,” Featherston said. “A tenacious team of dedicated investigators, Alton Baise of the Jefferson County Sheriff’s Office, Paul Arvizo of the Port Arthur Police Department and Mike Hebert of the Port Arthur Police Department, refused to let this cold case die. Joined by Assistant U.S. Attorney and prosecutor, Lesley Woods, this team worked day and night, turning over every stone to bring Allison’s killer top justice. That happened today.”

Because of the work of those investigators and prosecutor, the family of Allison Neil Clark now has justice.

“They joined forces and were able to take these two monsters off the streets,” he said.

Veteran PAPD Officer Hebert said the feeling on Thursday was hard to put into words.

“When this case went cold, Allison was still on our minds. Herbert Otis, who is not with us anymore, he broke his back on the job. One tip to him led to al that you see here. One individual trusted him and called to give pertinent information.”

Hebert and other officers kept in contact with the victim’s family, hoping they’d not lose faith in them.

“Paul (Arvizo) and I always talked about our kids. The proms, dance recitals and all that Allison will never see Cadence and MaKayla do. It’s always on our minds. The Clarks and Neil’s are the most amazing people.”

Under federal statutes, Martinez can face up to 100 years in federal prison.

In February, Ozzie Nelson Ibarra, 40, was sentenced to 35 years in federal prison in connection with the murder and other federal charges.

The men are said to be the ring leaders of a group of criminals, according to Featherston.
